same time the device is supported in a position where itmay `be` conveniently reached depending on the height of the `rwork-bench.and thedesire "l of 'the person manipulating .the same.

`lrnother distinctive feature` of my invention is to providean egg-candling device `which auto matically permits light-.rays to issue through .the bottom ofthe box when in raisedposition; .thereby illuminating the egg-crate which is placed beneath the device.

Yet? another .object oflrny invention. is -to provide an egg-'candling devicetin which the electric light socketjis easilyinserted 'or removed and which said light socket is held n rigidly in `place between the two cover-halveslof the boit` cover... l

`Still anotherobject of my invention `is to pro-- videran eggecandling device of simple,` economical constructiom which will occupy ibut* little space on the Wall and canlbe `produced.forlfonbparatively .small expense. l l l f My invention further comprises `the novel-Jdetails of construction `and arrangements of parts,

the embodiment of my invention illustrated I `show .merely informal `manner a box 10, pivotally attached to swinging arms 11. These arms `11 are also pivotally connected to a wallbracket i2; l

The =box lfU comprises a rectangular receptacleonsisting ein. `front-wall 13, side-walls 14 and 15 :and `the rear-walll. sidewalls 14 and 115 4and the .frontewall 13 are made preferably from one .piece `of sheet metal and spot welded to` the `.rearwall 16 in a manner as show-n in Figure `5. "The lowermost'ends of said walls are mitered and `bent over inwardly to form airame 17 and .an opening S18.

.As shown in `Figures 1, 2, 6 and-9, the top of the box 10 .is provided with a sliding cover 19 whichis .made in itwohalves. each half being provided at its abutment with .a centrally `disposed fsemi-circular opening 20, so as to produce afround aperture 21 when the sliding cover is in C'closed position.

:Both `mauves of said sliding cover 19 are slidably @mounted on outwardly .bent flanges 22 formedintegrally with the :side-walls 14 and -1'5 of box-10 (Figure 9).; Small stop-pieces 23, spot-#welded .tto the inner `side .of said cover 16, are provided for to prevent the latter from slid-` inglout ofiengazgement of the flanges l22 of `the boxlo when linserting fan lelectriclight socket 24. c

The mounting .of said'electric light-socket '24 is *extremely simple `sind is as `follows:

"The cover-halves fof cover 119 are manuallymovediapart bymeans of `the `bent-down portions of the cover oriiinger-holds 26 provided a't the `end or each cover-.half of said `cover 19, when f so .movedapart, the cover :assumes `a position-as shown .amil-Figures. After the lampsocket '24. is "inserted between Athe 'two coverhalvesszof `.fcover .19, said .cover-halves `are then slipped.: together as :shownin .Figure 6.

The edge of the now circular aperture 21 of cover 19 grips the socket 24, thereby holding the latter rmly in that position, ready for use.

The box 10 is mounted for up, down or side movement on a wall-plate 25 by means of two substantially parallel swinging arms 26 and 27 which are pivotally connected to said wall-plate 25 on a vertically disposed swinging-bar 28 which is provided at its upperand lower ends with pivot-pin extensions 29 and supported by angle-pieces 30 spot welded to said plate 25. These angle-pieces are provided with suitable. apertures 31 for the reception of said pivot-pin extensions 29.

To retain the device in a position as shownin Figures 1 and 2, or as shown in v dot and dash lines in Figure 3, I provide a horizontallyI disposed flat-spring 32, both ends of which are spotwelded to the wall-plate 25 and located about midways of the same. y A

' Co-operating with said flat spring 32 area pair of angular shaped retaining ,imembers 33 and 34, welded to swinging-bar 28 in a manner as best shown in Figures 1, 2 and 3. TheUhori# zontal arms of said retaining members 33 and 34 are rounded as at 35 and 36. These rounded portions produce a cam action in co-operation with spring 32 and exert a pressure against said nat-spring 32 when the device is in a position as shown in Figures 1, 2 and 3.

Due to the open space 37 obtained between said retaining members 33 and 34 when assembling, the device will retain that position until manually moved side-ways, which operation will slightly compress the flat-spring 32 and again relax the. latter when the device is swung ninety degrees to a position as indicated in dot and dash lines in Figure 3. When the device is in that position no pressure is exerted against the flat-spring 32until the device is again brought to a position as shown in full lines in Figure 3.

The rear wall 16 of the box 10 is provided with a vertically disposed and angular shaped support 38 on which is pivotally mounted a pair of parallelly disposed swinging arms 26 .and r27.

The other end of these swinging arms is pivotally connected to the swinging bar 28, as previously described. Both of said swinging arms 26 and 27 are p ivotally united by a connecting link 39, the lowerend of which is pivotally connected to the lid-operating lever 40.

This lid-operating lever is .mounted in parallel alignment with the swinging arms 26 and 27 and is pivoted by a pin connection 41 near the bottom of support 38. The lowermost terminal of said lever 40 is twisted, as indicated by the numeral 42 and strengthened by a short twisted strip 43 disposed in opposite direction oftwist 42l and spot welded tolever 40, as shown in Figure 5.

The twisted ends 42 and 43 are spot welded to the lid 44 which closes the opening 18 of box 10 when the device is in a position as' shown in full lines in Figures 1 and 2.

Access is-had to the interior of the box 10' for the purpose of inserting the' end of lever 40 by means of a vertical slot 45 (Figure 8) located inthe rear wall 16 of said box 10.

A bar 46 provided with notches 47 and a handleextension 48` is pivotally mounted on the upperswinging arm 26 about midway between the connecting link 39 and the verticallydisposed support 38. Bar 46 is held from moving sideways by means -of a guide-bar 49, one end of which is spot welded to the lower swinging arm 27 and the other end of which is held apart sufciently to permit free movement of said bar 46 by a shouldered pin 50 (Figures 1 and 7). This pin 50 also serves as a lock to hold the device in a downward position by means of the notches 47 in bar 46 and the coil spring 51.

To retain the device in an up position as shown in Figure 1 in dot and dash lines, a coilspring 52 properly anchored at 53 and 54 is used. Springs 51 and 52 are in an expanded condition when the device is down and in a contracted condition when the device is up.

The operation of my device is as follows:

Assuming that the device is secured to a wall ina dark-roomand is in a down position as shown in full lines in Figure 1 and a crate of eggs is placed beneath the box 10 as shown and it is further assumed that the lamp 55 in box 10 is energized. The operator faces the front of box 10 which is provided with a test-hole 56. When the device is in down position the bottom opening 18 is closed by the lever-operated lid 44, thus preventing light rays from lamp 55 issuing from the box 10, with the exception through the rounded test-hole 56.

The operator takes the eggs from the crate 57 and applies the same against the test-hole 56, so as to permit the utilization of the rays issuing through said hole 56 to inspect the condition of the egg. The eggs are then placed into another empty crate.

Since the device is produced preferably from sheet metal it may be found advisable to fasten a felt or leather padding around the test-hole 56 to prevent injury to the eggs. This would also allow the operator to place the eggs rapidly against the padding without exercising that extraordinary degree of caution which would considerably reduce the number of eggs to be candled at a given time.

To provide ample illumination, for instance, when itis necessary to replace crates etc. or in order to provide sufficient space around the work-bench when the device is not in use, the egg-Candler may be placed in an up position. The operator grasps the free end of bar 46 and forcesthe same rearwardly, thereby expanding spring 51 and at the same time releasing pin 50 from notch 47 and also releasing hand hold of the free end of bar 46.

This operation will bring the device in an up position as shown in dot and dash lines in Figure 1 of the drawing; it also will expose the opening 18r at the bottom of box 10, thus permitting the rays of light from lamp 55 to issue ample illumination to places where needed.

As designed the device furnishes light only where desired and the mounting of the device prevents it from being upset.

`The device may be applied in any desired way depending on the height of the work bench and the desire of the person using the same.

Though I have described with great particularity the details of the embodiment of the invention herein shown, it is not to be construed that I am limited thereto, as changes in the arrangement` of parts and substitution of equivalents maybe made by those skilled in the art without departing from the invention as defined in the appended claims.
